Everything that Christoph said, plus this:

These errors mean that it tried to use both NEON and AltiVec
instruction sets... which really doesn't make sense: no CPU supports
both, and neither apply to MinGW.
Did you enable these options manually?
Anyway, these error messages should go away if you turn them off (you
can use ccmake) or just start afresh in a new build-directory and
don't enable them, just run "cmake /path/to/eigen".
